Optimization of the conditions for energy extraction from a coupled-mode gasdynamic CO2 laser

A. I. Odintsov, A. I. Fedoseev, L. A. Fomenko
Abstract: A simplified model is considered of the physical processes occurring in the resonator zone of a gasdynamic laser emitting due to one of the vibrational transitions between levels of coupled CO2 modes. The energy characteristics of the laser are calculated and the energy extraction conditions are optimized for different active mixture parameters at the resonator input. An optimal energy extraction length is defined for a gasdynamic channel of constant cross section. The method developed is used to calculate the optimal nozzle profile in the resonator zone. Numerical calculations are made for CO2–Ar mixtures in which lasing takes place due to a transition with a wavelength of 18.4 μm.
